Philipp;
The left hand utility (cargo) door I had installed in my H-295 came from the wrecked JAAR's H-295 C/N 1240.This was the Helio wrecked by the tornado at Lakeland Sun-N-Fun. It was installed by Jim Metzler at his facility in Lancaster, SC. This was the JAAR's STC SA917SO for the swing back door.
I know Jim told me that JAAR's was out of doors to install because of a lack of certain parts to manufacturer the door. There are at least 2 other H-395/295 owners wanting doors. So there may be a market there to look at.
You could also try to find a wreck with the factory door and install that in your H-395.
Jim Metzler is at 704-843-6282.
